    I presume you mean mechanical boost gauges. I've heard nothing but amazing things about Defi gauges in general. I'm probably going to get rid of the Autometer mechanical gauge that I have, because of some issues I'm having with it. I think the Defi mechanical gauges are the D-series, but I could be wrong. Greddy and Blitz also make good gauges, but they might only be electric now that I think about it Hmm. A good gauge will run you around 100+, but something like an Autometer or VDO are somewhere around 45ish.

    edit: and dont feel bad about not knowing about modifying cars, we all started somewhere. Peruse the forum, theres a wealth of knowledge to be had

    I unhooked the vacuum line, the one that tees off the turbo. My car now holds a steady max boost of 16psi
